In this manner, the tire's steering becomes faster and more precise in its responsiveness to the driver's commands, while its structure is stabilized against the driving pressure affecting it in all weather. The dry zone's large shoulder tread blocks enhance the cornering and maneuvering ability and power. They provide additional biting edges that firmly grip the road surface and ensure a more secure drive.
